Green Dragons are also sometimes called “earth” dragons. They usually live deep within caves, and have power over the earth. They are capable of launching boulders at high speeds, and can cause earthquakes by slamming down onto the ground.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

NINER is part of an army of 12 Green dragons. They can't understand why they're part of an army but they are anyways. NINER is the pacifist in the group but if you attack and hurt one of her friends she'll go into a blind rage and attack any enemy that she sees. Even though she's a pacifist her love of the eggs, and the cave compelled her to join the army in order to protect what she loves the most.
